Abstract
Here, a superhydrophobic and catalytically active metal–organic framework (MOF) coating is reported by coordination-driven assembly of MOF nanoparticles and a catechol-functionalized polysiloxane polymer. This MOF coating can be fabricated by casting MOF-polymer precursor onto diverse substrates with varied coating techniques, for example, spray coating, bar coating, and dip coating. The catechol-functionalized polymer can not only coordinate to the open metal sites on MOF surface which enables the surface functionalization and assembly of MOF nanoparticles, but also allow non-covalent interactions with casting substrates—thus improving the substrate adhesion of the MOF coating. With the well-preserved porosity and surface hydrophobicity, the MOF coating demonstrates superhydrophobicity as well as improved catalytic activity toward the Knoevenagel condensation at room temperature. Such coordination-driven assembly approach can be extended to a range of MOF systems for preparing highly functional composite materials toward various applications.
